Index/Match not picking up with nth instances in list

Hey everyone,

I'm currently working on a rather large report to help my executive management team identify the number of "New" vs. "Current" customers who financed with our company during 2015 (sample chart shown below, and Excel attached). For the purpose of this sample, let's say I work for ABC Company.

Column "Analysis 1" is a helper column that I added to identify which customers are definitely current customers based on whether a date exists under "Inactive Date" that is +/- 15 days of the date under "Final Approval Date". If column "ABC Company Status" shows "active", then they are also a "current customer". Every other customer = "New Customer".

The formula that I'm currently using (and having trouble with) is under column "Current or New":
=IF([@[ABC Co. Status]]="Active", "Current Customer",IF(INDEX([Analysis 1],MATCH([@Grouping],[Grouping],0))<>"", INDEX([Analysis 1],MATCH([@Grouping],[Grouping],0)),"New Customer")).

• The issue I'm running into though is that this formula doesn't pick up on instances where the entry isn't the first instance in the grouping (even if it matches the criteria)... For example, Row 7 "Jake" should be a current customer based on the "Analysis 1" designation, as should Row 19 "Katie". I think that Small could be used.... but I'm not familiar enough with that function to know where to start with it (if it fits at all for that matter).

Any suggestions on how to solve for this would be much appreciated. Thank you in advance!
